David,

I was successfully able to get Snowflake cross-compiled and installed for OpenWRT and Entware as a package.

# opkg install ./snowflake_2.4.1-1_armv7-2.6.ipk
Installing snowflake (2.4.1-1) to root...
Configuring snowflake.

# opkg info snowflake
Package: snowflake
Version: 2.4.1-1
Depends: libc, libssp, librt, libpthread
Status: install user installed
Architecture: armv7-2.6
Installed-Time: 1670730403

# opkg depends snowflake
snowflake depends on:
libc
libssp
librt
libpthread

# opkg files snowflake
Package snowflake (2.4.1-1) is installed on root and has the following files:
/opt/bin/proxy
/opt/bin/client
/opt/bin/probetest
/opt/bin/broker
/opt/bin/server
/opt/bin/distinctcounter

# /opt/bin/proxy -version
snowflake-proxy 2.4.1

However, I still need to configure it within the torrc file and test it with its own listener in parallel with the loadbalanced OBFS configuration.

Thanks, again, for your guidance.

Respectfully,

Gary

P.S. I posted the Snowflake Package Makefile on the OpenWRT forum for reference:

Great! I'll work on compiling the Standalone Snowflake Proxy and see about implementing a loadbalanced OBFS & Snowflake configuration in parallel.

Thank you for your assistance.

Respectfully,

Gary
